1.0 INTRODUCTION
l
' By letter dated March 1,1995, IES Utilities Inc. submitted a request for revision of the Technical Specifications (TS) for the Duane Arnold Energy Center (DAEC).
Prior to the granting of this TS modification, Sections 4.5 and 4.8 of the DAEC TS require I
that various pumps and valves be tested once per three months. The TS Bases for l
Sections 4.5 and 4.8 state that the test intervals for this equipment "...are based upon Section XI of the ASME code."
If IES Utilities Inc. wished to alter the testing frequencies for any of the affected pumps and valves, it was required to seek a revision to the TS.
The change to the TS revises the surveillance criteria for testing certain pumps and valves in the Low Pressure Coolant Injection (LPCI) subsystem; the Core Spray subsystems; and the Residual Heat Removal (RHR) Service Water, Emergency Service Water (ESW), High Pressure Coolant Injection (HPCI), and River Water Supply systems from every three months to the testing frequency specified by the DAEC Inservice Testing (IST) program. The change follows the guidance in NUREG-1433, " Standard Technical Specifications, General Electric Plants, BWR/4," that generally defers to the IST program for determining the applicable testing frequencies for pumps and valves.
I l
2.0 EVALUATION The three month frequency for the testing of the subject pumps and motor operated valves is based on Section XI of the ASME Boiler and Pressure Vessel Code. DAEC has committed to follow and perform all required pump and valve testing in accordance with ASME Section XI (OM-6 and OM-10 respectively). Only those changes to the testing frequencies of pumps and valves allowed under 0M-6 and OM-10 can be made without requesting NRC approval via a relief request.
Further, the proposed change is consistent with the BWR14 Standard Technical Specifications, NUREG-1433.

The staff finds the proposed changes to the DAEC TS to be acceptable.
3.0 STATE CONSULTATION
In accordance with the Commission's regulations, the Iowa State official was notified of the proposed issuance of the amendment.
The State official had no comments.
4.0 ENVIRONMENTAL CONSIDERATION
S This amendment changes a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 or changes a surveillance requirement. The staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluent that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure.
the Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration and there has been no public comment on such finding (60 FR 18626). Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9).
Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendment.
5.0 CONCLUSION
The staff has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
